Still Having $$variable probs

[Anon]

Can anybody tell me why I get a warning message off the following code.

$htemp = "htmp$m"; //$m is increasing within a for loop

$$htemp = $$htemp + $$hother;

This is the error message I get.
Warning: Undefined variable: htemp

I only get on error message as it loops through the code.

The strange thing is the equation completes and gives the correct total but an error message is present. Any help would be appreciated.

can I see the loop?

The loop spans 2 pages..but its just a simple while loop.
$match is passed from a form on a prior page
while($m < $match)
{
$htot = "hgt$m";
$vtot = "vgt$m";

$$htot = $$htot + $temp;
$$vtot = $$vtot + $temp2;

}

And I get an error on the first time through the loop after that no errors and it all adds up like it is suppose to. How do I get rid of the errors?
